Single-Stage Mandibular Curved Ostectomy on Affected Side Combined with Bilateral Outer Cortex Grinding for Correction of Facial Asymmetry: Indications and Outcomes

摘要

Background Facial asymmetry combined with a prominent mandibular angle is common in the population. Its treatment involves two or three stages of surgeries. Generally, orthognathic surgery is a top priority. However, some patients with no severe occlusion disorders focus on the appearance and could not accept complex therapeutic procedures. This study evaluated the surgical effect of en bloc mandibular angle-body-chin curved ostectomy (MABCCO) combined with traditional mandibular angle curved ostectomy (MACO) and bilateral outer cortex grinding (OCG) to correct facial asymmetry and a prominent mandibular angle.
